What is the Unstructured Data Storage Function (UDSF)?
A.
This network function exposes 5G Core Network functionalities available to 3rd parties, so that 3rd party capabilities and events may be securely exposed by the Network Exposure Function (NEF).
B.
This network function is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.
C.
This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized – Unstructured – data.
D.
This network function stores or retrieves subscriptions, profiles, and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.

Question 6
You and a colleague are discussing the challenges to be resolved in order to make digitization and automation a reality in all industries. He is arguing that the solution is to have faster access connectivity, but you don’t agree. You are trying to convince him of the need for an end-to-end solution. The new 5G network should be built end-to-end to enable industries’ quest for value. What arguments can you provide to support your position?
A.
Increasing throughput is not enough. A faster and automated transport network, a distributed cloud where applications would run depending on their latency and reliability requirements, a core network that automatically handles any type of access, and a security framework to guarantee the security in every layer of the network are also needed.
B.
The network consists of many layers that include access, transport, core, cloud, and all of the applications running in the cloud. Increasing throughput in access is not enough. The bit rate needs to be increased in all of the other layers as well.
C.
Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.
D.
Increasing the throughput is enough. There is no need to change the network end-to-end.

Question 7
What is the main benefit of Cloud RAN?
A.
Increased cell coverage
B.
Better latency
C.
Reduced cost by centralizing some radio functionalities
The network of the future is the key to supporting the digitization and automation of many industries. This network should support diverse requirements from different applications using it. To do that, the network should have a new architecture. Which of the following best describe the elements of the new 5G end-to-end network architecture?
A.
Wireless Access, Optical Transport, and a dedicated Core Network for wireless access running in a Central Cloud.
B.
Multiple access types (not only wireless), Optical Transport, Multi-cloud, and dedicated Core for every type of access.
C.
Public sector element, a smart city element, a health element, a transport and logistics element, and an industrial element.
D.
Massive Scale Access combining many wireless and wired access types, Smart Network Fabric as transport (combining optical and IP network elements, controlled by SDN), a Universal Adaptive Core network supporting all access types, a Multi-cloud system including central, regional, edge, public, private, and hybrid cloud, and Automation and Analytics providing flexibility in the network to serve different applications.

A company is planning to offer services to different cities worldwide so drones can be used to scan disaster areas to help identify victims’ locations quickly, organize evacuations efficiently, and save lives. Drones will be connected to a 5G network. The company is planning to offer two applications running in the cloud – one to manage drones through remote control while the other offers live video streaming to drone operators. As a 5G professional, you are asked what are the network requirements for those two applications?
A.
The drone control application needs very low latency to maneuver around obstacles, while the video application would need less latency. Both applications would be running in the central cloud.
B.
The drone control application needs low latency and high reliability from the network and should run in the edge cloud. The video application needs higher throughput but it is not sensitive from the latency and reliability point of view. It can run in a central cloud.
C.
Both applications should run in the edge cloud because the drone control and video applications both require low latency and high reliability from the network.
D.
The drone control application should run through a central cloud. The video streaming application should run in the edge cloud because it carries much data, and that is expensive to run through the central cloud.
